Title: Instrument for applying liq. - has valve which can only be opened when inner housing is in correct angular position
Inventor: KIMURA MASARU
IPC: B65D47/42
Filed: 1991-02-09
Abstract: A instrument for applying a liquid, such as a hair dye, has an inner housing (1) which contains the liquid. A valve (4) fitted at the end of this inner housing controls the flow fo the liquid to the brush (3). The valve (4) is opened by pushing it forwards by exerting pressure on the outer end (5) of the inner housing (1). The inner end (24) of the inner housing (1) has a non circular cross-section. An internal transverse wall (28) has a hole of matching contour. The end of the inner housing can only be inserted into this hole if it is in the correct angular position so the valve (4) can only be opened when the housing is in this position. USE - Applying hair dye.

Title: Photographic image production using pointwise illumination of light sensitive carrier material - focussing CRT generated light beam, controllable in position and intensity, sharply on carrier material by lens
Inventor: WAGENSONNER EDUARD DIPL ING
IPC: G03B27/32
Filed: 1991-08-28
Abstract: The method of producing photographic images involves using a light beam controllable in position and intensity generated by a cathode ray tube. The CRT screen is sharply focussed on the carrier material using a lens. The screen material afterglow duration, which is long compared to the stimulation time, is used for illumination. The afterglow duration is selected so that a reduction in sensitivity of the light sensitive material does not occur because of reciprocity errors arising for very short illumination times. ADVANTAGE - Eliminates reciprocity errors in light sensitive material and minimises image generation time.
Patent DE-4133409-A1 (DE)
Inventor: THUERK JUERGEN DR RER NAT
IPC: F24C3/08
Filed: 1991-10-09
Abstract: The invention offers a simple and economical mounting possibility for gas burners in molded parts made of a brittle-friable material, such as glass, glass-ceramic or ceramic, by means of which gas burners can be mounted without stresses, in a leakage-proof and gastight fashion in cooking surfaces of such a material without having to impose a restriction as to a special appliance and/or a specific burner type. The molded part which is made of the brittle-friable material, is the sole support for the gas burners, however, if the molded part breaks, the gas burners will drop onto a lower metal support so that the gas feed lines do not rupture.

Patent DE-4137123-A1 (DE)
Inventor: BECK ERHARD DIPL ING
IPC: F16K31/06
Filed: 1991-11-12
Abstract: The invention concerns a pressure-control valve with a valve-obturation element (4) which is mounted so that it can move longitudinally in the valve housing (17). The valve-obturation element (4) allows the size of a port between a first pressure-medium connection point (2) and at least a second pressure-medium connection point (3) to be adjusted, the size of the port depending on the position of the valve-obturation element (4) relative to the valve seat (18). In order to reduce valve noise, passageways (1, 1') for the pressure medium, which can be closed off or opened one immediately after the other by the valve-obturation element (4), are located between the first and second pressure-medium connection points (2, 3), thus giving a variable valve-opening area.
